At its core, cyber security is about protecting systems, networks, and sensitive information from unauthorized access. Organizations must secure their networks, endpoints, cloud platforms, and user identities to prevent threat actors from gaining access. Protecting the organization's network from both external and internal threats is essential to maintaining a secure digital infrastructure. Tools like Active Directory are commonly used to manage authentication, user privileges, and security policies within organizations, helping to control access and prevent privilege escalation.

This requires implementing security controls such as firewalls, encryption, multi-factor authentication, and continuous monitoring. An effective cybersecurity program must adhere to a set of sound security principles. Strong cyber security frameworks help reduce security risks posed by phishing, ransomware, and insider threats. Incident response strategies are crucial for organizations to effectively handle cybersecurity incidents. Many organizations are hiring chief information security officers (CISOs) to manage cybersecurity risks and strategies. Security departments are enjoying a larger share of the enterprise’s budget to enhance cybersecurity measures.

Cyber threats can target a wide range of victims from individual users to enterprises or even governments. The first cybersecurity patent was granted to MIT in September 1983 for a cryptographic communications system and method. Secure Sockets Layer (SSL) was released by Netscape in 1994, becoming a core protocol for secure online transactions. Cybersecurity professionals are in high demand due to the increasing sophistication of cyber threats.

A data breach occurs when sensitive information—like financial data, intellectual property, or user credentials—is exposed without authorization. Data breaches often result from unpatched software, weak passwords, or successful phishing attacks. Breaches frequently target information systems that store and process critical data, putting the foundational components of organizational IT infrastructure at risk.

Training teaches users how to spot warning signs, avoid risky behavior, and safeguard digital data. Phishing and Social Engineering Awareness Training teaches how to recognize and report fraudulent attempts to steal sensitive information. Employing phishing and social engineering simulations regularly tests employees’ ability to identify malicious tactics. A majority of data breaches result from human error, making awareness training crucial for beginners. Such incidents can also disrupt essential digital services, impacting business operations and customer access.

With regulations such as the General Data Protection Regulation (GDPR), organizations must reduce exposure to security vulnerabilities to avoid legal and financial consequences. Building a ‘human firewall’ through training significantly reduces the risk of data breaches caused by human error. The late 2000s saw a rise in data breaches, prompting governments to implement regulations requiring notification of breaches. In 2014, Yahoo announced a cyberattack affecting 500 million user accounts, later believed to impact 3 billion accounts.

Industrial control systems (ICS) and operational technology (OT) are critical infrastructure used in manufacturing, energy, and transportation. Although once isolated, these systems increasingly connect to the internet, expanding the attack surface.

Cybersecurity 101 training introduces learners to ICS risks, such as outdated software, weak segmentation, and targeted attacks designed to disrupt physical operations—or even stealing intellectual property. Motivated by politics, social activism, or greed, threat actors reach every corner of the globe to intercept, exfiltrate, or disrupt the ever-increasing flow of data. Cybercriminals, nation-state hackers, and hacktivists are all finding new and innovative ways to compromise digital assets. Organizations are increasingly allocating significant resources to cyber defense due to the growing sophistication of cybercrime.

In 1971, the Creeper worm was created by Bob Thomas and spread using the ARPANET, marking one of the first instances of a computer worm cyber attack. Ray Tomlinson created Reaper, the first antivirus software, in response to the Creeper worm. The Morris Worm, released in 1988, was another early example of a computer worm; it spread to thousands of computers and was the first case where a person was convicted under the CFAA. In 2003, the hacker group Anonymous emerged, becoming known for its decentralized online activism and cyberattacks. The Computer Fraud and Abuse Act (CFAA) was enacted in 1986 to address hacking and has been amended multiple times since.

Cyber attacks take many forms, from brute force attacks, such as password guessing attempts, to sophisticated malware campaigns. Common techniques include:

Some prevalent cyber threats include malware, phishing attacks, denial-of-service attacks, and man-in-the-middle attacks. Phishing is a type of cyberattack where threat actors masquerade as legitimate companies or individuals to steal sensitive information. Ransomware is a type of malware that encrypts a victim’s data until a payment is made to the attacker. The WannaCry ransomware attack in May 2017 targeted Microsoft Windows systems and propagated through the EternalBlue exploit. Training helps learners identify threats early and take preventive measures to reduce the impact of future security incidents.

Ethical hackers play a key role in identifying vulnerabilities and strengthening defenses against these types of attacks.

Artificial intelligence (AI) and machine learning (ML) play a growing role in both cyber attacks and cyber defense. Attackers use AI to analyze behavior patterns, craft more convincing phishing messages, and automate brute force attacks. On the defense side, AI enhances endpoint detection, monitors anomalies, and strengthens threat detection. Antivirus software became popular in the early 1990s, initially scanning compiled code against a database of known malicious signatures. Cybersecurity 101 introduces users to how AI can be used responsibly to reduce risks and improve organizational resilience. Password Security and Authentication emphasizes creating strong, unique passwords and the importance of multi-factor authentication (MFA). The demand for security professionals with offensive security skills is growing every year.

Integrating security controls into continuous delivery pipelines ensures that security is embedded throughout the development process, enabling more agile, secure, and efficient application deployment.
